D = 13" reel, machine-ready EIA-481 embossed plastic tape (400 parts per full reel).B = Less than full reelIn tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter
D instead.

Maximum power into specified load that causes less than a 40°C temperature rise. Measured at 1 kHz with a 14.4 Vdc supply for the 2-Ohm load and a 21 Vdc supply for the 4-Ohm
load. Output Power table shows typical output conditions. Tested using TAS5414A evaluation board from Texas Instruments.

3

Inductance is for each winding, measured at 100 kHz, 1.0 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer.

4

DCR is for each winding, measured on a micro-ohmmeter at
25°C. For other operating temperatures, use this DCR at Temperature calculator.

5

SRF measured using Agilent/HP 8753D network analyzer.

6

Total harmonic distortion + noise measured at 20 W into a 2-Ohm or 4-Ohm load at 1 kHz with a 21 Vdc supply.

7

Isat: DC current (typical) at which the inductance drops the specified amount from its value without current.

8

Irms: Current applied to both windings at the same time that causes the
specified temperature rise from 25Â°C ambient. This information is for
reference only and does not represent absolute maximum ratings.

Ambient temperature range:

−40°C to +125°C with Irms current, +125°C to +165°C with derated current
